`One .of the o'utstandingobjects ofV the' present invention isto.provide an improved headlight in whichtlleligliting unit is acl-'Ijustable within the 'casing or housing, where-vk by the proper focusingyot the lightrays isV accomplished? v The invention furthermorecomprehends a means forming-part of the. lighting unit which functionsto eliminate the glare from thegheadlight upon the eyes .'offtheYdrivers of'appro-aching vehicles, pedestrians or other persons in thepath of movement of the ve-y v hicle while producing upon theroadwayVsuiicient illumination. r` y' As a further object, the inventionconteIn-f, plates an improved headlight ,structure fin x which: thelighting unit is capableo'being readily removed fromiandf applied to thevcasing or housing.

Then the set. screw Q5 is loosened,the slide 25, which supports a reflector, may be raised or loweredtherewith or the slide may be swung horizontally so that the reflectoris horizontally swingable within the casing. l/Vhen the set screw istightened, the slide is maintained against turning or sliding movementto holdthe light-ing unit and reflector in adjusted position.

In order to provide means for shielding the eyes of the drivers of'approaching vehicles or other persons from the direct glare,

va shield or deflector blade 32 is provided which is secured to atransversely disposed rod or shaft 33. The rod or shaft is mounted inbearings 3e carried by the forward end of the reflector 14 atapproximately diametrically opposite points. T he bearings are disposedslightly above the center of vthe reflector, asg clearly illustrated inFigure 1 of the drawings. The rod or shaft 83 is provided with arearwardly directed terminal 35 disposed eXteriorly of the reflector 14,and a detent member 36 is secured to the outer side of the reflector andformed with a plurality of notches 37 into which the .free end of theterminal 35 is selectively sprung due to its inherent resiliency. The

rear medial portion of the deflector blade 32 projects rearwardly in asubstantially arcuate formation as illustrated in 38'so that the properintersection of the light rays is accomplished to shield the eyes ofpersons in the path of the headlight from the glare. T his arrangementadmits of proper adjustment of the shield or deflector blade 3Q and'when properly adjusted in combination with the adjustments of the lampand reflector in the housing or casing admits of the proper illuminationof the road in advance of the vehicle while preventing glare.

Having' thus described our invention, we

claim:

The combina-tion with a headlight casing and a reflector of the beamprojecting:T type mounted therein, of approximately diametricallyopposed bearing brackets mounted on the forward edge of said reflector,a horizontal rod journalled in said brackets, a glare shield carried bythe rod, a rearwardly and inwardly bent crank arm carried by one end ofvthe rod, and a vertically disposed plate mounted on the outside of thereflector having arseries of notches in its edge to accommodate the freeend of the crank arm, whereby the glare shield may be selectively tiltedand locked in various positions or" adjustment.
